AC/DC converter in a tiny package offers an impressive power density

RECOM has developed a low cost 5W AC/DC converter in a tiny 1” x 1” package, offering an impressive power density of 7.7 Watt/inch³. Their RAC05-K series are AC/DC converters specially designed to supply IoT and factory automation applications. These modules provide high performance without additional components necessary and due to modern and efficient manufacturing lines, the company is able to offer cost savings of up to 50% compared to similar products. Their low no-load power consumption of only 75mW and excellent light load efficiency make them ideal for “always-on” IoT systems. Standard output voltages are 3.3VDC, 5VDC, 12VDC, 15VDC and 24VDC with sufficient power to operate relays, data gateways and building automation nodes. A universal mains input voltage range from 85VAC to 264VAC makes them suitable for worldwide use. The modules feature a 60ms hold-up time at 230VAC input, which means that missing mains cycles do not affect the output. The company fabricated these converters into a lightweight fully encapsulated plastic casing taking up only a square inch on the PCB, therefore allowing them to be designed into space constrained applications. These series operate over a temperature range from -25C to +50C at full load (up to +70C with derating) and are output over-voltage and short-circuit protected. An EMC Class B filter is built in without the need of any additional components, further saving space and cost. The RAC05-K series are fully certified to UL/IEC/EN60950-1 and UL/IEC/EN62368-1 with CB reports. They are CE-marked and come with a three-year warranty.
